Agree about weight of Khyams. Also, the doorway is very very low, a bit of a pain when it's wet. I've had two over the years, quality has really suffered. The groundsheet is pathetically thin and fragile so you end up getting the sps under-groundsheet sheet. More weight, more bulk. Absolute piece of piss to put up, not much fun to get back into the bag, especially one-handed. Shame the old inflatable igloos disappeared, and Karsteins are obscenely expensive. If it's only occasionally light use have you considered the "pop up" type spring hoop fame job?
